Sliding Gate Valves

We are a major supplier of a comprehensive range of Sliding Gate Valves that is used to control the gravitational flow of granular materials. Using the heavy duty 100/150/200 ISMC steel with a steel blade, hard steel, or S.S, the value frame is constructed. We can achieve actuation of Slide Gate Valve in many ways, pneumatically for fast action, manually for slow movement, hydraulically for power and electrically for precise positioning. When handling granular products, a molded urethane inlet liner provides an ideal blade seal. Moreover, while handling fine dusty material, additional frame seals should be used. These valves are basically used for stopping and controlling the flow of abrasive slurries.

Rotary Airlock Valves

Rotary Airlock Valves

Avail from us an efficient range of rotary airlock valves that is also referred as rotary air feeder and is extremely used for dust discharge device. It is better than gravity operated double flap valve as it gives continuous discharge and has a better air tightness. While discharging dust, the valve prevents gas leakage through the inlet opening. This valve consists of a cast or fabricated housing that is provided with a rotor and a shaft. The fins of the rotor are welded to the shaft. The volume of rotor is determined by the empty space between the two fins. On each rotation, dust that is held in the pocket is discharged. And depending on the applications, material of constructions are decided whether cast iron mild steel fabrication should be used or stainless steel.
